Change subject: mainboard/emulation/qemu-aarch64: Add new board for ARMv8
......................................................................

Patch Set 15:

I believe it's time to review.

I relocated BOOTBLOCK code into DRAM successfully and reverted the change in /arch/arm64/armv8/cache.c that means we can use a BSS section.

Now, I can make coreboot.rom for QEMU/AArch64 and execute it via:
$ qemu-system-aarch64 -bios ./build/coreboot.rom -M virt,secure=on -cpu cortex-a53 -nographic -m 1024M

The result of this execution is "Payload not loaded" because I put an empty payload. However, The comment "Payload not loaded" indicates we are ready to pass the execution to the payload.

Could you review this CL?
